Balanced equation:2H2S + 3O2 → 2H2O + 2SO2
Mass of H2S = 1 tonne = 1 x 106 g
Molar mass of H2S = 1x2 + 32.1 = 34.1 g mol-1
No. of moles of H2S = mass/(molar mass) = (1 x 106)/34.1 = 2.933 x 104 mol
Mole ratio H2S : SO2 = 1 : 1
No. of moles of SO2 = 2.933 x 104 mol
Molar mass of SO2 = 32.1 + 16x2 = 64.1 g mol-1
Mass of SO2 = mol x (molar mass) = (2.933 x 104) x 64.1 = 1.88 x 106 g = 1.88 tonnes
